Ethnic groups are universal and unique to human societies. Such groups sometimes have norms of behavior that are adaptively linked to their social and ecological circumstances, and ethnic boundaries may function to protect that variation from erosion by interethnic interaction. However, such interaction is often frequent and voluntary, suggesting that individuals may be able to strategically re...

The purpose of this research is to test whether descriptive norms, or cognitions about typical beliefs, values, and behaviors of one’s group, can explain cultural influence in the domains of blame attribution and harm perception. In Study 1, using participants from the United States and South Korea, the authors find that individuals with lower (vs. higher) collectivistic descriptive norms ascri...

Social norms are cultural phenomena that naturally emerge in human societies and help prescribe and proscribe normative patterns of behavior. In recent times, the discipline of multiagent systems has been modeling social norms in artificial society of agents. This paper reviews norms in multiagent systems and then offers exploration of a series of norms in a simulated urban traffic setting. Usi...

It is very encouraging that the authors of this special issue are giving renewed attention to the contribution of social norms to the creation and maintenance of culture. Such a focus has long been called for (Pepitone, 1976), but rarely achieved up to the present. Focusing on norms is one way of recontextualizing social psychology, and another is to make sure in our studies that we sample a fu...

Understanding cross-cultural aspects of emotional overinvolvement (EOI) on psychosis outcomes is important for ensuring cultural appropriateness of family interventions. This systematic review explores whether EOI has similar impact in different cultural groups and whether the same norms can be used to measure EOI across cultures. Thirty-four studies were found that have investigated the impact...

Normative cognition – a uniquely human cognitive capacity ’Normative cognition’ is a ’mongrel’ concept covering human cognition of symbolically mediated normative information. Humans have social and cultural cognition of which normative cognition is a subset. Humans can produce, distribute, acquire and implement social norms and values. Normative cognition requires certain cognitive skills such...

Within- and between-nations differences in norms for experiencing emotions were analyzed in a cross-cultural study with 1,846 respondents from 2 individualistic (United States, Australia) and 2 collectivistic (China, Taiwan) countries. A multigroup latent class analysis revealed that there were both universal and culture-specific types of norms for experiencing emotions. Moreover, strong intran...

We present an agent-based model designed to study the cultural evolution of age-at-marriage norms. We review theoretical arguments and empirical evidence on the existence of norms proscribing marriage outside of an acceptable age interval. Using a definition of norms as constraints built in agents, we model the transmission of norms, and of mechanisms of intergenerational transmission of norms....

Contour lines totally fix the structure of leftcontinuous t-norms. For each t-norm, these contour lines are determined by the corresponding residual implicator. Most properties involving residual implicators can now easily be translated into properties involving contour lines. As the portation law expresses associativity, we dispose of a powerful tool for constructing left-continuous t-norms. I...

Diverse lines of theoretical and empirical research are converging on the notion that human evolution has been substantially influenced by the interaction of our cultural and genetic inheritance systems. The application of this culture-gene coevolutionary approach to understanding human social psychology has generated novel insights into the cognitive and affective foundations of large-scale co...
